Unlike many other programs, you install CQ WCM by using a "Quickstart" self-extracting jar file. When you double-click the jar file for the first time, everything you need is automatically installed. The CQ quickstart jar file includes all files required for:
the CRX 1.4.1 repository (a JCR-170 compliant repository and Apache Sling), virtual repository services, index and search services, workflow services, security and a Web server.
the CQ Servlet Engine (CQSE). You can run CQ WCM without an application server, but you need a Servlet Engine. Both CRX, and therefore CQ WCM, ship with Day’s CQSE servlet engine, which you can use freely and which is fully supported.
The first time you start the jar file, it creates an entire JCR-compliant repository in the background, which may take several minutes. After this startup is much quicker as the applications have been installed and the repository already created.
This section contains detailed instructions on how to install CQ WCM using the Quickstart jar file.

These instructions apply only to CQ version 5 and higher. Versions prior to 5 used an installer rather than a quickstart jar file. For information about installing previous versions, see the appropriate documentation at docs.day.com. |
